Adeen FlinkerIntracranial electrophysiology of speech perception and production

Speaker: Adeen Flinker, Assistant Professor, Department of Neurology, NYU

The seamless process of perceiving speech and then fluently producing a response requires a cascade of neural processing across cortex. Among the most fundamental, and highly debated, principles of the neurobiology of language are the nature of hemispheric asymmetries in speech perception as well as the unique role of the Inferior Frontal Gyrus in speech production. In this talk, I will present how leveraging computational techniques together with temporally resolved neural recordings can shed light on these principles. I will provide a testable computational framework for speech hemispheric asymmetries as well as argue that the Inferior Frontal Gyrus integrates information across cortices and is chiefly active prior to articulation per se.

About Adeen Flinker

Adeen Flinker received his PhD in Neuroscience from the University of California at Berkeley in 2012. After completing post-doctoral research at New York University, he joined the New York University School of Medicine as an Assistant Professor of Neurology in 2017. He has appointments with the NYU Neuroscience Institute, NYU Biomedical Engineering and NYU Cognition and Perception.

Dr. Flinker's research focuses on the electrophysiology of speech perception and production. He leverages behavioral, non-invasive and invasive electrophysiology in humans to tackle basic questions in the perception and production of speech. During his PhD work, he used Electrocorticographic (ECoG) recordings over Broca's area to establish that the region is not active during word articulation but rather integrates information from temporal cortices prior to articulation and constructs an articulatory plan which is forwarded to motor cortices. The detailed characterization of the spatiotemporal dynamic in the inferior frontal cortex prior to speech articulation, as well as subsequent suppressed temporal cortex responses to self-generated utterances at a millimeter scale have been since replicated across many laboratories. During his postdoctoral research, he tackled the question of hemispheric cortical asymmetries in speech by providing a novel computational approach to characterize the acoustic space that drives differential cortical responses, unifying previous prevailing models. His approach was tested in psychophysical dichotic paradigms, non-invasive neurophysiology experiments (MEG) as well as neurosurgical recordings (ECoG and sEEG). Dr. Flinker currently oversees ECoG recordings at NYU and his lab focuses on clinical and basic intracranial electrophysiology of language. His research has been published in top journals and is funded by three large NIH grants and a collaborative computational neuroscience NSF award.
